There are hundreds of different altcoin projects on the market. So, you can't generalize all the altcoins as a whole, obviously. Of course, only the good coins will survive. This is the nature of things, man. 
its too much altcoins and project from developer almost the same and don't have a different from previous project so many inevestor not interested with new project.hope the developer have a new for future altcoinYeah, I agree that there are too many similar altcoins, but there are some unique, cool projects too. It is just hard to find proper ones because of the whole promo bombing.
